Pruning a Phalaris arundinacea 'Picta'
To maintain the striking variegated foliage of Phalaris arundinacea 'Picta', pruning is advisable. In late winter or early spring, before new growth begins, cut back the plant to ground level. This encourages fresh, vigorous shoots to emerge, which will display the plant's characteristic white and green striping. The upright, bushy growth habit of this species ensures that it will swiftly rebound, reaching its full height of 70 cm with a lush, variegated display by summer.
